[gotcha] Suggesting taking certain antibiotics \(like tetracyclines or fluoroquinolones\) with milk or calcium-fortified foods to soothe stomach upset

Advise taking these antibiotics with water and avoiding dairy/calcium supplements within 2 hours, as calcium chelates the drug, rendering it unabsorbed and ineffective.

Journey Context:
Agents might suggest 'take with food/milk' to mitigate GI distress, a common pattern for NSAIDs. For fluoroquinolones/tetracyclines, this chelation trap silently nullifies the antibiotic, leading to treatment failure and antibiotic resistance without immediate symptoms.
